That, at least, is what she suggests in the second part of her interview with Oprah Winfrey, which airs this Sunday (8 p.m. ET) on OWN.

“It’s very comforting to have someone that knows everything about you, that respects you, understands, has gone through the similar things,” Kim tells Oprah. “I can really relate to his mother passing. He can really relate to my father passing. I mean, there’s so many similarities in our life that … I feel like I’m at a really happy, good space.”

Kim credits her chemistry with West to the couple’s long friendship: The two met a decade ago and have been friends for “six or seven years,” she says.

“I don’t know why it took so long for us to get together,” Kim says, “but I think I needed to go through all my experiences.”

That’s not the only relationship that Oprah explores on Sunday, however. During a sit-down with Khloé Kardashian and hubby Lamar Odom, Oprah asks, “Do you feel pressured to make this marriage work because it’s in the public?”

Says Khloé: “I don’t feel the pressure by outsiders. … I’m not someone who’s easily influenced by the public. … My marriage is my real life. I feel the pressure from me – from myself – to be a great wife.”

Khloé also reveals to Oprah that she doesn’t read gossip about herself in tabloids or blogs, but she does hear about it from her publicist, her sisters or other family members.
